T @UIL/17mm www concer/1,:

siding at Washington, in the District of Colum bia, and VICTOR R. ROTH, resid'i ng at Philadelphia, in the county of Philadelphia and State of Pennsylvania, citizens of the United States, have invented certain new and useful Improvementsin Non-Refillable Bottles; and we do hereby declare the following to be a full,

1o clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to a novel construction in a bottle, the object being to provide a bottle that can be filled in the ordinary manner, but which 'cannot be refilled after having been sealed.

The invention consists in the features of construction hereinafter fully described and zo claimed.

In the accompanying drawings, forming a part of this speciiication, Figure 1 is a central vertical section of a bottle constructed in accordance with this invention. Fig. 2 is a Fig. 3 is a perspective view of the protecting-plate. Fig. 4 is a transverse -section on the line a 4 of Fig. 1. Y v

Referringnow to said drawings, 1 indicates 3o the neck of the bottle, which is of ordinary construction, with the exception of an interior groove 2 and an opening 3 below said groove. The opening 3 is a vent controlled by a button or plate 4. on the inside of the 3 5 neck, to which is connected a small wire or pin 5, extending through said opening 3 and passing through the spring 6 on the outside of the neck. This spring 6 normally holds the button or plate 4. tight against the inner 4o face of the neck to close the vent and by pressure is expanded to allow the button to move away from the opening, so as to permit air to enter the opening 3. The vent is situated so that it can be operated conveniently when the bottle is tipped for the purpose of pouring the contents therefrom.

The groove 2 is situated a sufficient distancey from the mouthof the neck to permit the entrance of a cork of ordinary construc- 5o tion and has an abrupt upper wall 7, which extends outwardly almost to the outer face of `the neck, so that a very thin or frangible portion is provided, while the other wall 8 of this groove is angular or inclined and gradually meetsthe inner face of the neck. Situated 5 5 within the said groove 2 is a -valve-casing 9, having a circuitous passage 10, the ends of which are situated on opposite sides of the casing at the upper ends thereof; The upper end of the circuitous passage 10 is at one side 6o of the casing, and just below the upper end t-he casing is made with the platform or shoulder 11, while the lower end of the passage 10 is provided with an outwardly-opening valve 12, adapted to close against the valve-seat 13. This valve-casing is preferably made of rubber and is forced into the neck of the bottle and into the groove and is preferably glued or cemented therein by a suitable cement between the outer wall of the casing and the 7o outer wall of the groove. To protect the overhanging flange 14 at the upper end of the casing, a protecting-plate l5 is placed within the neck of the bottle and suitably glued or cemented therein and provided with an opening 16, situated over the upper opening 10. This protecting-plate 15 is preferably made of glass, and in this manner the insertion of an instrument for the purpose of tampering with or holding the valve l2 open is pre- 8o vented. It will be understood by reason of the inclined wall of the groove 2 that pressure sufficient to force the valve-casing into the lower end portion of the neck of the bot- .tle will cause the frangible portion of the neck to break.

In use the bottle is filled in the ordinary manner, after which the valve-casing and protecting-plates are inserted and secured, and Vthen the bottle is corked in the usual 9o manner. In opening the bottle the cork is irst removed, after which by compressing the vent 3 when tipping the bottle air enters the bottle and allows the liquid to pass out through the opening valve, which closes when the bottle is inan upright position. After the contents are emptied it is obvious that the bottle cannot be refilled wit-hout removing the outwardly-opening valve, which allows the outiiow of the liquid. roo

Having thus described our invention, what we claiin as new, and desire to secure by Letters Patent, is-

A non-refillable bottle having a neck with a groove therein of elongated forni and having inclined walls divergin g toward the mouth of the neck, a truncated conical valve-casing situated in said groove and formed with a circuitous passage therethrough intermediate of which is a horizontally-disposed shoulder located under the upper exit-opening of the said valve-casing, the said valve-casi 11g having a lower opening controlled by an outwardlyopening valve, a protecting plate situated above the valve-casing and having an opening therein alining with the outletopening of said valve, the said neck also having a vent-opening therein below the valveeasing, a covering for said vent located on the inner side of the neck, a pin attached to said covering and to an outer spring, and a removable cork iitted in the neck above the protecting-plate. suhstantiallyas and for the purpose specified.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
